To all whom it may concern:

Be it known that 1, WILLIAM C. MA'rri-rms,

a citizen of the United States, and a resident of the city of Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Sprmkler's, of wh1ch the followingis a sprinkler nozzles mounted u'pon symmetric ally grouped distributing pipes, and it consists in the improved construction of the sprinkling devices, and in the manner of connecting the same to the pipe risers, as hereafter fully described in connection with the accompanying drawings and specifically pointed out in the claims. j I 5 V The drawing is a sectional View showing a portion of a distributing pipe with sprinkler fitting attached,-embodying my inven-f tion. 1

The distributing pipe or riser a, as shown, is provided with a separately formed capplate 6, whichis removably secured to the pipe a in any suitablemanner, and which,

while it forms no part of the sprinkler proper, serves as an advantageousmeans of attaching the latter as hereafter described;

The sprinkler fitting D comprises a cylindrical nozzle body d which is exteriorly screw-threaded to fit a central aperture 0 in the cap 6; intowh'ich aperture said nozzle body is screwed from the under sideofthe cap so that the top of said nozzle is, preferably, flush with the top 'of the cap, and so that the fitting can :only be removed after the cap itself has been disconnectedjfrom the pipe (1. Forming part of thefittingD, and connected with the lower portion of the nozzle body d by wings e e, is a transverse carrier -bar f for the sprinkler -plughereafter described, said bar thus depending, from the cap 6 within the-pipe a, when the.

parts are assembled in operative position.

The sprinkler-plug G, which is formed with a spreader-head g of suitable shape as desired,has a stem h passing, axially downward through the nozzle aperture 01; said stem being connectedby means of its screwthreaded lower end'h, as shown, with a corn tral aperture f in the carrier-bar f, and having a rigid collar 76 which seats upon said bar so as to positively locate the spreaderhead g in determined position relative to the nozzle aperture 01' to produce a desired spread of the passing liquid. This collar is, in addition to serving to properly locate the spreader-head of each sprinkler-plug of a series in determined uniform position as s'tated,-1s made to serve a further purpose of considerable practical importance; the occasion for such additional use arising .from the ascertained fact that the nozzle apertures 01 areapt to become clogged or obstructed by deposit of greasy or other adhering material from the passing liquid, sufliciently to objectionably, afi ectv the discharge. To provide for conveniently remedying this trouble, I form the collar is of a diameter adapted to loosely fit the nozzle aperture 03, and with a cutting edge is, whereby the operator is enabled to quickly and thoroughly'clear said nozzle orifice when required, by merely disconnecting the sprinkler-plug from the carrier bar f and forcibly withdrawing it through the nozzle orifice so as to carry with 'it the obstructing material;

In order toproperly maintain the sprinkler fittings it is necessary to make them of non-rusting material such as brass; and it becomes a matter of considerable importance, particularly in plants employing a large I niunber of widely distributed sprinklers as in sewage disposal systems, to prevent the unauthorizedremoval of such parts. In my improvedconstruction it will be seen that this is practically accomplished by connecting the sprinkler fittings to the pipe (1, through the medium of the iron cap I), so that it can only be gotten at by first removing said cap; while at the same time the maintenance of the sprinklers in proper working condition is-made easy by adapting cap, ofa sprinkler fitting comprising a nozzle body removably secured to said apertured cap from the under side of the latter and provided with a depending transverse carrier-bar, and a sprinkler-plug having an I axial stem the lower end of which engages the sprinkler-plug to serve as a cleaning means for the nozzle orifice as described,

said carrier-bar and the upper end of which aperture and adapted to serve as a cleaning 13 provided with a spreader-head.

I I device for the latter substantially as set forth. in 2. In sprinkler, a nozzle body provided i In testimony whereof, I aflix my signature, with a depending transverse carrier-bar, and l in the presence of two witnesses. sprinkler plug having a spreader-head and 1' WILLIAM C. lVlATlTTIITAS.

an axial stem with a lower end engaging Vitnesses: said carrier-bar and a collar seating thereon, CHARLES R. WERNER, said collar being loosely fitted to the nozzle P. F. SoHoLL.
